I like your idealism. And it’s clear that you’re passionate about your work. The world would be a better place if everyone felt that engaged. There’s no doubt Twitter has radically enlarged the public sphere. At the same time, no revolution or paradigm shift is frictionless. Delivering a vision of global interconnection depends on public infrastructure and responsible social engineering, to foster respectful discourse. I hope Twitter continues to embrace its responsibility here. Because disruption for its own sake without attention to the daily, local world being disrupted is very 22 year old.
